Seed #2981 is one entry in the Instruments 1-by-1 pillar of Calm Sound Archive. It is generated in the browser with the Web Audio API, so nothing is streamed and nothing is downloaded: the same seed number always produces the same piece of audio.
What you are hearing
Triangle tones with a breathy second partial and a slow attack, close to a bamboo flute.
The musical material uses F Lydian at 70 BPM, tuned to 174 Hz. A binaural offset of 4 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it when you want a single instrument and nothing else — no bed of noise, no percussion, no vocals. This seed leans toward study & focus and runs at 70 BPM, so it moves slowly enough to sit under conversation or sleep.

How to listen
- Press play and choose a session length between five minutes and eight hours.
- Headphones give the binaural layer room to work; speakers still play the track but flatten the stereo image.
- Keep the volume where you can still hear the room. The fade-out at the end of a session is ten seconds, not a hard stop.
